Hi does anyone have any experience of running Sn 99 Cu0.7 Ag 0.3 solder in their waves? Also is there any reliabilty data available? I think it may also be called C7A3. All I can find is a brief mention in a table in IEC 61190-1-3 2004, and on a pr

Here are some general rules for lead free wave solder: Noble aloys will cost more. Period. The cheapest metal on earth is lead. Costs can only go up in Lead Free. Consumer grade and class 2 electronics will most likely use Tin / Copper for wave.

Oh silver and its...improved solderability over tin / copper. BS if you ask me. Look to your flux and thermal profile for wetting spread. Ask yourself just how much "wetting spread" do you need to fill a barrel? I have the same 100% barrel fill

With twenty five machines working with the LFB227/S on our little island it does seem to work well. Wetting is good compared to Tin/Copper and flow is comparable to 63/37. Biggest problem sticking 3 - 4 % Ag in a solder ignoring the patents and royal

What aload of rubbish - prove it, we have over 320 users in the UK alone using the SACP0307 solder with great results, and the biggest advantage they have is they can multiple source the solder not stuck to one company who has purchased the patent an

Although greatly publicized and many papers on the subject, I wish to hear experiences from the field from professionals who have migrated from SnPb wave soldering to PbFree wave soldering. I am being pushed by one of my largest clients, an internati
